Mass flow rate is a fundamental concept in fluid mechanics and thermodynamics. It refers to the amount of mass that passes through a given cross-sectional area in a fluid system per unit of time.ย
- แน (m-dot) is the mass flow rate (kg/s),
- 2๐ is the constant representing the circumference of a circle,
- r is the radial distance from the center of the cylindrical system,
- l is the length of the cylindrical region through which the fluid is flowing,
- ๐ (rho) is the density of the fluid, and
- Vr is the radial component of the fluid velocity.
